The other day when I was shopping in the grocery store I could not believe what I had found! I actually found air filters for my central heating and air conditioning system in the grocery store and they were on sale. I do not know what air filters for central heating and air conditioning systems or anything for that matter were even doing there. After shopping at this grocery store for 6 years I had never seen heating and air conditioning system air filters or any other kind of air filters in the grocery store. I guess maybe this was something they just started and are trying out. But I can tell you because they were on sale for such a good price I actually bought a nice handful of them so I do not have to go to the store for air filters for a while. This will not only save me money by the great sale that I got on these, but it will also save me gas for my car as well. Also, if this becomes a regular thing where the grocery store sells air filters for central heating and air conditioning systems, I never have to worry about going to the hardware store again and I can just go to the grocery store to buy the air filters for my central heating and air conditioning system. Even if they are not on sale, it still saves me money because the grocery store is much closer to me than the hardware store. It is just a good deal all together and I am happy I found it.
